- Specification sheet:
Overview
The ultrathin (less than 20 µm), flexible, stretchable, adhesive, and ultrabroadband-capable silver nanomesh can be cut by household scissors into any shape and placed on virtually any surface for label-free chemical sensing of analytes from low to high concentrations. This silver nanomesh SERS sheet provides a Raman signal enhancement factor of 106 or higher by electromagnetic enhancement. The minimum acceptable size is 1 mm x 1 mm, meaning that up to 900 SERS chips can be produced from a single SERS sheet.
Applications
- Urine drug testing
- Sweat analysis
- Pesticide residue inspection
